Rinnai RXP160iN – Sensei RX Series Indoor Tankless Water Heater
The Rinnai RXP160iN is built for homeowners who want dependable performance, intelligent efficiency, and long-term value from their hot water system. As part of Rinnai’s flagship SENSEI® RX Series, this model delivers a powerful yet balanced solution: compact in size, super high efficiency, and ideal for homes running multiple fixtures throughout the day.
Designed for modern living, the RXP160iN provides continuous, on-demand hot water with precise temperature control, even when showers, faucets, and appliances are running at the same time.
